A system 10 comprises a cryogenic engine 20 utilising a cryogenic working fluid WF and a heat exchange fluid HEF. A cryogenic refrigeration system 60 cools the contents of a container 100 and includes a source 80 of cryogenic fluid CF, a heat pump refrigeration system 70 containing a refrigerant RF, and a heat exchange system 90 through which the cryogenic fluid and refrigerant exchange thermal energy with the contents of the container. The heat exchange system includes a cryogenic fluid outlet 92 and the cryogenic engine includes a cryogenic fluid inlet 22 for receiving cryogenic fluid from the cryogenic fluid outlet. A sub-cooler 120 is connected between the cryogenic fluid outlet and the cryogenic fluid inlet for exchanging heat between the refrigerant and cryogenic fluid. A heat exchanger 160 may exchange heat between the refrigerant and the heat exchange fluid before the heat exchange fluid enters the engine to extract heat from the refrigerant. The heat exchanger may receive heat exchange fluid from a source 110 and may include a condenser 170 for condensing the refrigerant from the sub-cooler by heat exchange with the heat exchange fluid.
